Deleting initiators from an initiator group
You can use the Initiator Groups tab in System Manager to delete an initiator. To delete an initiator from an initiator group, you must disassociate the initiator from the initiator group.
All of the LUNs that are mapped to the initiator group that contains the initiator that you want to delete must be manually unmapped.
Click Storage > LUNs.
In the Initiator Groups tab, select the initiator group from which you want to delete the initiator, and then click Edit.
In the Edit Initiator Group dialog box, click the Initiators tab.
Select and delete the initiator from the text box, and click Save.
The initiator is disassociated from the initiator group.
